CGTalk - Caustics burnout

I have my object here, and I'm concerned about the ground being burned out.

Some stats.
OGO_hikari SSS: Many different parameters, but I don't think is the cause of the hotspot. I could be wrong.

Color filter: on

Light affecting cuastics:
2% intensity
point light

Caustics:
1%intensity
5000 accuracy
40 softness

Radiosity:
interpolated
50%intensity
.5 tolerance.

Um...I'll take a wild crack at it...

Reduce the diffuse on the floor surface.

Diffuse on the floor is 80%, do you think even more?

I tried diffuse at 50%, and the hotspot is still the same intensity.

i'm curious...could you place a point light beneath the object with a negative intensity value and also set it to a small falloff to suck away the amount of light interacting with the floor to kill some of the hot flashing? just a thought. make sure it only affects the floor object though.

sometimes being negative can be a positive thing.

Good idea, I'll give it a try.
